For many people wanting to experiment with algae or even those who are serious about mass production there are usually problems with space or seasonal restrictions they have to work with. This reactor design is an attempt to produce a reactor that will run indoors year around safely with a …

Most large reactor arrays have one failing in that if any part of the reactor is damaged it can compromise the entire reactor. Imagine 500 gallons of algae water flowing where ever it wants to go and you get the idea… With this in mind this system is modular system …

Our algae photo-bioreactor framework is 43 ¾” tall x 17 ½” wide x 2 ½” deep. It consists of 5 vertical 1 inch tubes. We built this unit for a 2 ½” deep window sill. It is pictured here sitting on a light box. A bit about this window unit …

Overview: This is mostly just a fun article that I wanted to write for the simple reason of accessible information for anyone. Basically this is a example project that demonstrates how extremely easy it is to use the Arduino based platform to control high voltage devices via a webpage. This …

Overview: So this project has been lying around for a while and I finally found some time to write it up. I was inspired with several of the other popular microcontroller based laser instruments that have been floating around on the web over the last year. Ultimately I wanted to …

Overview: So photography is not only a hobby of mine, but also more or less absolute necessity for what I do here on invent geek. That being said I have always been appalled at the high prices for photography equipment and accessories and I find myself thinking that I could …

Overview: For some time I have been experimenting with algae and it has become a bit of a passion of mine. Enough of a passion in fact that I have built a sister site to InventGeek.com called AlgaeGeek.com where I have more of a focus on reactor designs that I …

Overview: This project is the next in a series of DIY Photography Studio Equipment projects we are doing to improve the quality of the imagery on our site as well as in preparation for the launch of our new sister site dedicated to photography equipment projects. The next major component …

Overview: Tiz the season for burning projects. With this in mind I wanted to build my personal variant of the popular propane based fire popper. The problem with propane is it always burns with a very bright orange fireball. I love pyro chemistry, and specifically coloring agents. So the natural …

Overview: So this is kind of a fun project overall. The real star of the project is the control box that is a small elegant control system with easy to use plug outlet type connections. We have 12 isolated outlets on this control box for all sorts of fun larger …
